ANNUNGIATOR. I

Specification of Letters Patent. Application liled December 3. 1.906. Serial N'n-'lo.

Teall inkom 'it may conce-m: y Be it known .that/lj LAFAYETTE S. SCOTT, a

citizen of the United States, residing at? Rochester, "in the county of' Monroe and 4State of New York, have invented a new and *I proved Annunciator, of which the follow-Jy .in is a specification.

' his invention relates to annunciators of'.

l that class adapted to use upon xnoving vehii 10 -cles for indicating successively the different stations along the route and additional therei to advertisin matter, as for instanoe,`merely:

a concern Orbusiness" house the name of a street or station, and more escharacter above described which may be 'ap-4 plied to and operated automatically on ve- -cles having a' pre determined path of; travel, preferably s uch as a railway.

1n order that any one or more of the names' .of the stations or the advertising matter exhibited in connection therewith may be;

` changed, either one singly or both together,

as desired, I. provide a series ofcharacterbari'ying forms each independently operable.

by means of elements 'on the car or 'vehicle' adapted to be engaged and Operated by suitable engaging elements disposed along the pathway of the vehicle. In carrying out my invention, l also provide, preferably adjacent to each and every station Aor pre-determined location for exhibiting a `name and sigma series of tracks located at each'such station or stop and on the side thereof ad`acent to the next succeeding station in the fine of travel yof :the vehicle or 'cai'. I prefer to provide these tracks .in two series, the .purpose of which will be explained later, and on the car l provide an annunciato:` comprising a series of independently operable character-carrying forms Ior wheels iu vconnection with means whereby only one ,at a time of the characters' carried by each form or wheel mayl be brought into view. For the above reason, I provide, preferably, two aotuatingmcchanisms for each of such forms or wheels independent of the actuating mechanisms for any other ones of such character-carrying forms or wheels. Each of such actuating mechan-Y Y isms for each of such .character carrying forms or wheels is under lthe control of-a separate element carried also by the car orfve-f Suitable engaging or operatingwmembers,

prctipe'rly supported on such tracks in the of such elements. lt is im ortant that all of the character-carrying w eels should j have an initial position Where they exhibit only a blank.

In the drawings I' have shownvthat einbodiment of m. present invention adapted to use upon ra' Way cars forindicating sucoessively each next stop or station which the car make and in connection therewith any brief advertising matter, as for instance, the name of an advertiser in connection with the nearest sto to his place `ofl business Which the car W1ll make. ,A .A

vIt is obvious thatbetweeneach element projecting from the car and the correspondrammenta. 14,1908.

ing character-carrying wheel Orform there should be asuitab for Which purpose I have found an electromavnet with its armature answers admiraby. The source of electric energy and its location. are immaterial. Bythus providing independent and independently operable character-carrying forms or wheels in the annunciator and the above indicated means for -operatin such character-carrying Wheels, I amk enab ed first to return alllof such Wheels to their zero -or initial position exposing a blank simultaneously and I am also enab ed' to advance such wheels simultaneously step 'by step from their initial ypositions to the e connecting mechanism,

point where Athere is exposed on each one thereof the proper character in the desiredv 90.'l This is a matter of considerable importance,"

indication to be given by the annunciator.

as it is desirable that the annunciator should exhibit thc desired information for the maximum possible portion of the period of time which is consumed by the car or vehicle in passing .frein any one sta-tion to the next s uc ceediug'station, and this I have found a very `important feature in cases wherestations are q,u1te ucar together.

Forthe sake of avoiding confusion in the .drawings and to illustrate more clearly the more .essential features of my invention, I

'have illustrated and described -an embodiy ment thereof comprising only 22charactercarrying Wheels arranged 1n a single row and eachI of' such wheels `carrying 37 characters and a blank; the invention, however, .is not limited to any particular number of Suche'y *wheels or `any pantioiilar number ofcharac i" hicle and projecting outwardly therefroml @ters thereon, or vet again to any .partcula4 and .adapted to be engaged and operated byf Figure l shows in meclianical diagramn niatic 'vii-w the relation ol' the tracks at three stations, alongthe path of travel of such a vehicle, hoth for returning the lettijlr-carrying forni or wheel eacli.to its zero or initial point andy `for actuating such wheels each- `rom such '/.e'ro point'to the point where they Vwill'each exp-ose to view the desired character. Fig. 2 shows in mechanical diagram the arrangement of the engaging projections on each ot the tracks at one ot the statii'ins indicated in' Fig. l. ln Fig. 2 eachof the tracks oi each series is shown in side view so as' to clearly illustrate the arrangeinent'of `the engaging rejections thereon and at the lett in Fig.' 2 t ie centers of the engaging projections' on `the tracks are arranged in tine broken vertical lines marked i to 38, inclusive, and. underneath and engaged by each ot the extreme lelt hand projections on suoli tracks there is diagrammatically indicated a roller suoli as iscarried hy each element projecting from the car, the p ur pose oflwhich` will he explained later.' Similarly, to the right, in Fig. '2 there is shown a series of tracks carrying'projections adapted, hy their engagement with the corresponding elements projecting lrom the car, to advance the desired one of the character-carrying forms orv wheels each to such a point as will result in exhibiting to view in the. annunciator the de! Fig, 3 shows in in'echan-'I sired indication. ical and electrical diagram the means toractiiating` any one ot the cliaractercarrying lorms in such a way asto return the saine to its zero or initial position exposing to view hlank thereon.v Fig. 4 shows in similar mechanical and electrical diagram the means 'for actuating any one of the character-carrying forms from the zero or initial position to the positionv where there will hc exposed thereon the proper character in the desired indication. Fig. 5 shows=`a iront View of' part ,ofthe.. annunciator with a art ol" the case reniovedto showi partially t ie `internal arrangement ol the parts, while Fig. 6 shows in a similar way a rear View of the annun-v ciator with also a part of' the. case removed. liig'. 7 shows in interior end vic-w a portieri ol the upper part of a car with my amiunciator in position therein and exposing-to viewtliat indication 'tohegivei'i just after passing one of the stations, as will he explained'. Figs. S and 9 show did'erent views of a modified larrai-igement olt the mechanismy comprising f ically, as l'eioasz-Canal St., Worth St. and

ing in the manner to be explained toJreturn'.

the character-carrying forms or wheels in my amiunciator to the zero or starting point'. 51m-T1 constitute a second series of tracks located at each such station and to the right of the tracks T and,also carrying projections and operating, in the manner to hey explained, to advance `the desired ones of the character-carrying Wheels to the point Where they will give the desired indication in the annunciator. In Fig. l the tracks are shown in `diagrammatic plan viegw and hence the projections on the under side thereof are not shown.

Refer now to Fig. 2,.-In this the. tracks TA and T1 with the projections t and t1 thereon arranged inaccordance withthe plan and method of operation of ymy invention in the illustration hereinafter given. A series ofrollersa are seen adapted and arfigure there is shown diagraniinatically and in side view ranged to be engaged by the projections t 2 carried 'by the tracks T. y To the right ot the trac-,lis T are seen tracks T1, some of which have no projections thereon, while others ot them are provided with projections.

A se-l riesci rollers@ are seen as ladapted and ar` v.

ranged to be engaged hy the projectionsy t1 on the tracks T., The rollers c and c are.

revoluhly supported and carried by thel elcments which t ey arer so supported that as the car travels throughout its pathway or course, the projections t on the tracks T are in the path 'of the rollers a and the projections t1 on the tracks T1 are in the pat will he explained. i lteler now to Fig. 3,-In this ligure there.

of the rollers c, as

rejecting from the car and from., Y

is shown di'agraniatically the mechanism `and connections.between one roller (1f and its coromittedl therefrom exceptsuch as are necessary to show thc connections between one ol such rollers (l. and its corresponding charactercarrying wheel. "l represents one of the tracks with the projections tvthereon. Z represents a portion ot the roof of the car and 2 a projection carried therelijY and arranged transversely ol' the car. 'j This projection z carries a series olI pivotal supports 1, in each one ol' which there is .pivoted the right hand end ol' a lever A, the left hand end ol which is hil'urca ted and each such memliei' thus l'o'rmed is again hil'urcatwl or slotted to engage the ends of a pin extending horizontally through the upper end ol' the plunger A adapted to move vertically through and irespondingfeliaracter-carrying lorm or wheel.` r i 'i his ligure hemg'diagrammatic, all parts are j arenas' be guided in the opening therefor' in the projection b4 extending upwardly .through vthe roof of the car at the upper left hand corner of the frameBof theannunciator. Thelever A carries a clamping socket A1 within which is'secured the lower end of thevertically dis,

posed arm A2, on the upper end of which in turn is secured the clamping member A?, in which there is revolubly supported a roller a, rIhis vertically disposed arm A2 is sufficiently 'ilexible or elastic to overconieany undue shock or strain upon the apparatus, but it lever A downwardly to its low errnostg'iositionu should have sufficient rigidity to force the each time that the roller a at the upper end thereof engages a projection t on the track A The frame work B of the annunciator carries a series of lugs or ears b comprising lpivotal supports for the horizontallydisposed` levers a, one only of which is seen in .the figure,

and between the-right-handend 'of which and the portion bj of thejframe work of the annunciator a coiled spring a? is seenlo'perating to force theright hand vend of'the lever a downwardly and thus raising 'the left hand end of such lever, which carries nith it the plunger A4 engaging and resting' on-the left hand end thereof and therewith' also the lever A, and thus operating normally to hold the left handy ends of such levers in their uppermost positions permitted by the washer. a7 on the plunger A4 and opposing the' action of the engaging members t onthe rollers a.

l he lever a carries an insulated contact,(,y f 1n ahnement with which is'seen Aa contact a4 ported upon the shaft Y, which extends transversely through the annunci ator and' parallel with the face thereof. On the under l side of the left hand end of this lever I there vof the. lever I.

may preferably Vbe secured a non-metallic strip adapted to prevent a magnetic con tact between the armature hk and the core of electro-magnet H. Parallel. with the shaft Y there extend. through the annunciator rods X and X, the function of which will be eX- plained later. y 'Io the rod X is secured the lo er end of a spring 11:1. the upper end of which is secured to a suitable hook depending` fromthe underside of the right hand end 'lhe s ring :v1 operates to draw the ri ht handen of the lever I downwardly an to hold the armature 7L awaY from `theelectro-magnet H. On the right handend bf the lever I there'is pivotally sup ported a pawL all, the lower end of whiclvis Supported from the portion b of' held in engagement with the teeth p on the ratchet wheel P by means of. the spring i. operating in the way lclearl indicated A spring x3 secured at its left'fiand end to the rod X and having its right hand end secured to a downwardly extending projection carried by the" pawl aff, pivotally supported on .the rod X, operates to hold the pawl in 'engagement with the teeth p of the ratchet wheel P in such a way as to prevent a haekward rotation thereof. The extreme throw or movement of the lever I is soproportioncd relatively to the teeth p, of the ratchet n heel P that for each stroke of such lever l the wheel P is advanced onetooth or'notch p thereon in a clockwise direction.

From a-sourceof electric energy, indicated diagrammatically at U1, whether the same that propels thecar or otherwise is immaterial, a Wire 2 leads to the electro-magnet H while the wire 3 leads to the insulated screw' connector a5 from which aeXible connector leads to the electric contact a, while from the electric Contact d4 the wire 1 leads to the. other terminal of the coil of the electro-mage net H, whereby it will be seen that each time the roller a engages a projection t on the track T the electro-magnet H is energized b v lbeing connectednp in a circuit with the source of electric energ)r U1, whereby it will also be seen at once that for each one of the projections t on the track Tv the ratchet wheel P is advanced'o'ne notch or tooth thereon. It should be noted, however, that t is ratchet wheel P is nota perfect wheel in that there is va space. of one uncut tooth whereby it will at once be seen that such ratchet wheel can be advanced only to the position indicated in Pig. 3 andthat any subsequent, energizing thereafter of the electro-magnet II will not advance such ratchet wheel P from such pos ition so shown in' Fig. 3. This position corresponds to the initial or starting position of Ithe character-carrying Wheel connected to the ratchet wheel P in the manner to be here'- inafter explained. There is one wheel P and its actuating leverI, an electro-magnet H, a lever A and roller a carried thereby and all the other above "described connections bc- -t'ween-such just above mentioned elements for each and every character-carrying wheel in my annunciator. It will at once beunder-A stood then that each of such charactercarry` ing wheels, regardless of its angiilar position at any one time andthe eharacterexposed to view thereon, is returned to the zero or initial position when the carcarrying such annunciator passes by or under the tracks T with the wengaging.members t thereon, usuch engaging members t on each of such tracks beingY of course arranged in the pathway of the correspending roller 'e `earned by the lever A, which comprises one of thetwo 'operating elements for each character-carryingwheel prc- .i jccting from-the'ar.

' has its lower end connected to the ro lleler now to Fig. 4, which shows the mechanism l'or advancing any one. cha-rmLrw carrying wheel trom its zero or initial posi\ tion to the point where there will be exposed to view thereon the desired character. '1" is a traclecarrying the engaging projections t1. Z is the top of the car, z the projection secured thereon and z the pivotal support 'for the. lever (l -carrying the socket C for the upwardly-extending arm (l2, constructed and operating in the saine way as the arm A2 referred to in the description of Fig. 3, and having detachably secured thereto the inember C1 in which is revolubly supported the roller c adapted and arranged to beengaged b v the projections t. The plunger C with a washer c thereonjs guided in the hole therefor in the port-ion b4 of the frame B of the annunciator and is operably connected with the lel't hand end of the lever (.f in the saine wajr that the plunger A is connected to the lever A. 'lhe lever cl is pivoted in the bracketor ear b, two such ears may be used for each lever c if desired, carried by the portion b1 of the frame B of the annunciator and extending underneath the roof of the car. A spring cgy operates to force downwardly the right hand end ol: the lever c1, in the manner already described with reference to the lever al, and this lever c1 carries an insulated coni' tact c from which a flexible connector leads to the connecting screw c'. The armature c 'carries an insulated contact c3 in alinement with the insulated contact c4 on the flange b2 on the fraineB. An electro-magnet K is sup orted on the portion b of the frame Wor B of the-annunciator and has one terminal of the coil thereof connected by wire 4 with the contact c4. From the other terminal of this electro-magnet K wire 5 extends to the source of electric energy U1, which is connected by Wire 6 with the contact screw c5. The lever J is pivotallysupported upon the shaft Y and carries upon its left hand end the amature c in alinernent with the core of electro-magnet K. A thin metallic stri j is secured on the under side of the left han end of the lever J inthe same Way and for the same purpose as already mentioned regarding the strip 'i and the lever l. A s ring :v2 X and its upper end connected to a'hook depending from the under side of the lever J near the right hand end thereof. A spring pawl jl is pivoted to the extreme right hand end of the` lever J and is held inengagement with the teeth p* ol: the ratchet wheel P* 'by means of the spring secured and operatingjn the manner clearly indicated in Fig. 4. 'Bhe ratchet wheel l is also connected with the character-carrying l'orln or ,wheel revolubly supported upon the shaft WQ In Fig. 4 the lower end of the spring actuated pawl jl carried b the lever J seen just at the point'of one o the teeth p1 and just before engaging the under surface thereof, and the pawl 'il on the lever l immediately behind it, is seen partia-lly in dotted lines. lmmediately behind the ratchetwheel l1 is seen that portion ol the ratchet Wheel l comprising the s )ace ot the uncut tooth thereon, showing tlirough between-the teeth on the wheel P1 at the, upper righthand side thereof. l

From the foregoing description it will at once be seen that, each time the roller c engages a projection t* on the track "l", the electro-magnet li is energized by being connected in circuit with thc source oi electric energy U1. The extreme stroke or throw' ol' the lever J is so proportioned relatively to tfhe teeth p1 on the ratchet wheel l" that each sti-olie el such lever J operates to advance the wheel P1 in a clockwise direction one tooth or notch p1 thereon.l 'lhe wheels l and l)l are secured together and*.preferably on the same endof a spool or two-tlanged wheel PL'.

ln Fig. 4 a portion of the ratchet wheels P and Pl are broken away at the center in order to show more. fully the construction of the character-carrying wheel or forni l secured thereto, such wheel l2 comprising two llanges p2, one only of which being Ythe one*l next to the observer is seen. Each olI the flanges p2 has a series of holes thcretlnough near the outer edge in which there are pivot,- ally supported the inner endsof the character-carrying flaps Qthe outer ends ol' vl'our of which are seen as supported upon the ledge c just within the face of the annunciator, and 'practically' at'right angles with the lower one of which is seen the first or exposed one ot" several others of such tiaps Q occupying )racticalljr vertical positions. As the wheel P is actuated or advanced one notch or tooth, at a time, by the energizing of the electro-magnet K, the different successive ones ol' the character thereon. Of these character-carrying flaps Q'there are provided on cach wheel one for each character within the y range of characters called for by the indications which it is desired to give and also a blank llap. The number of such tia )s-then, in accordance with the scheine outlined in Figs. 1 and 2, will bc 38, including such blank. As the starting point for each wheel is that point where it shows the blank, there is necessitated onlyv 37 projections tf'on the track T in order to bring into view succes-n sively each character thereon, the iirst and 'last ofv such projections, operating to bring into view A and ltween these extremes anv desired character may be brought into viewo'n any one wheel at any stationaccording to the number of projections t1 on the track'T1 at that station.

'As seen in Figs. 5 and 6, l prefer to arrange a track T and a track T1, with the projections t and t* thereonrespectively, adjarespectively, and beflaps Q are brought into view., exposing the cent to each other and to arrange the vrollers,

l a and-c and the supporting levers A and C similarly adjacent to each other and the corresponding ratchet wheels P and P1 respectively adjacent vto, each other and at one and the same end of the flanged Wheels orspools il?z and with the Wheel P1 tothe left or out side of the Wheel l".-

. tor, `as indicate in Fig. 5. -As the flaps Q' Refer now to Figs. 4 and 7 ,-near thev top and'across the faceof the annunciator is seen a transparent sheet E, preferably of glass, -belund -Which lthere may be suitably 'supperted and exposed to viewan opaque sheet El having cut out therefromthe letters -comprising the words The 'next stop is.

It is. quite immaterial how this indication is 'secured provided that it is permanent and is llegible by daylight and also by a light, such4 .as the incandescent lamp k1, suitably arranged and sup orted within the* annunciaare pivoted at their inner ends within the flanges of the wheel p, the outer edge of each one describes -practically a quarterV of a circle Ams as it falls from the ledge e and just as it comes into view. It is important rthen that there be `suitably supported beneath the transparent sheet E a transparent sheet F which 'may preferably be bent to conform approximately to a quarter of a cylinder, the axis of which coincides with or passes through the pivotal's'upports for those aps Q which are that the inner edge of the ledge e be straight andparallelwith the alined plvotal supports for such ofthe fiapsQ-as are at any one time exposed to View, and also that the inner edgev of such ledgele be arranged relatively to the shaft l W and Ithe character-carrying wheels revolubly-supported thereon substantially as shown in 4.

Refer now to Fig. V7,-- in this ligure the annunciator is shown as giving the proper indication after the car has passed vthe tracks Tx located on the right hand side of the'Canal St. station, as indicated in Fig. 1,

and this indication stands or remains until the rollers a, carried by the levers A are engeared by projections t on the tracks T at th"` right hand or down town side of the Worth St. station, and thereafter the rollers c onythe proper levers C are: engaged by pro- |jeotjons t? on the corresponding tracks T at the right hand or down town side of the Worth St. station in' such a way as to cause the annunciator to give the next desired indication, the character and nature of such operation being substantially the same as already described in reference to the indication caused to begiven by the annunciator just ,after leaving Canal St.

I desire to call attention to the fact that the electro-magnets H and K and their armatures h and /c respectively are shown only diagrammatically as well as the electric connections 'with the coils of such electromagnets. Vln practice, Iprefer to make use of an electro-magnetic construction in which the only break in the .magnetic path comprises the operative stroke .ofthe armatureto and from the core of the electro-magnet, such and other details oi construction comprising non-essential features of my present in'vention, are indicatedonly in diagram.

-When more than oneV annunciator is made use of in a car, that ispone at each end, or .when several annunciators are used on different cars, it will of course be understood that such connections Willbe made between the source of electric energy and the coils of the electro-magnets in such different annunciators' as will result in simultaneously operating the corresponding character-carrying Wheels in all of such annunciators, whereby all-,of such annunciators will simultaneously give the same indication to an observer facing them, and it is quite immaterial what .system oi connections is resorted to for se- I curing this end y Refer now to Figs. 8 and 9 which show .different positions of the parts of a modified arrangement of a projecting element or lever carrying rollers adapted to be engaged by projections t on a track T. or tjon a track T1. Ziis part of the roof of the car,

B a part of' the frame work of the annunciator beneath thesame, z. the projection carried by .the roof of thecar Z and comprising Aa seat for receiving the pivotal supports z for the lever N, on-Which at its upper left hand end there -is pivotally supported the threearmed lever N1, on each of the two upperv arms nof which in 'turn there-is pivotally supported a roller a, at sucha distance apart asto at least span the space on the track T covered by one. of the projections t. The

Alever'N carries at its upper lclt hand end also the horizontally movable and spring actuated plungers a5, operating to hold the downwardly extending arm nl of the threearmed lever N1 in a central vertical position practically such as seen in Fig. S, which is the normal position vfor the parts, except as one of the rollers a carried by thevhorizontal arms rnl on this lever -N1 is engaging by a projection t on the track T. Check nuts n are provided on thc outer ends of the plungers a5 to limit, their movement and the-'springs maintain the adjustment ot' the parts to the normal positions just above described. Between the lower arm n ol" this lever and the upper vend of the bell crank lever n there is pivotally secured the connecting rod or link n. The lever u? is pivotally supported in an ear or lug 23, and of these ears z3 there may be, ii' desired,

los

two for eaclrof such levers n3, and they are. secured, preferably, to the yframe B or' the annunciator in any `suitable way not shown. The left hand end oi the horizontal member of thej'bell crank lever n is yb iiiireated andis connected to the 'plunger A, having the ywasher a thereon "and working through the projection b1earri'ed` bythe frame work b of' the annnucia'tor," in -'substantially the same manner asalre'adyjnlly described in referringto Figs. 3 and 4. in, regard to the 'connections betweenthe, plungers A* and C1 and the bifurcatedends of the levers A and C respectively.. The lever; N has an arm n4 extendingto the right troni its iv-' otal support, such extension carrying va down- Wardly extending stop 'adapted to engage; the upper surfacep the horizontal `plate' carrying the ears 22 to prevent the spring; s from forcing the left. hand end of the lever n upwardly beyond the proper limit there# for. The. arm ntonthe iever Ncarries hook adapted to be engagedbythefupper end 'of the spring s, the lower end of whichis 25 secured'tothe top of thecar Z1 and tends/v to hold the lever N in the position indicated in Fig. 8, with the roller a, on the three-armed lever N 1 pivoted thereon, iirinly up against the under side of the track. In Fig. 9 the parts are shown in the position' which they assume when the righthand roller a is engaged by and oppositethe center of one of the rejections t on the track T, for which positionit will be seen' that theI plunger A1 has been forced downwardly so f that the lwasher a"A thereon rests upon the upper surface of theprojection b1 carried by 'the frame of the register'B. j lt will be seen at onceby reference toFigs. .8 and Q that 'the position kof the plunger A1,. Whether up or down, is (lependeiit. quite entirely upon the angular dispositionfoi the. three-armed lever N1 regardless, lwithin the moderate range called for by variations in the load on the'car, ofi the'height of 'the left hand .end of the pivotal support for' this three-arined lever N1 pivoteu at vthe upper left hand end of the lever N, i I have found it desirable to make use of'U the arrangement just described to compensate forvariations in the load on the car in order that the position of the plungers A4 and C4 may be dependent upon the engagement of the'rollers ci and c by the projections t and t1 res ectiveiy, and independent of theA height of tiiepivotal support for the levers carrying such rollers as arfected or modified by the load on the car.

The foregoing detailed description of the construction and operation of the different features-` and parts of. my annunciator it4 is f believed, suiiici'ently explains the operation of my annunciator to make further description thereof unnecessary herein.v I'will add, how-' ever, that when it is desired to change the indication given by the annunciatonit is onlyI neeessary to change the arrangement 'oftheprojections t1 on the tracks T1 at that station preceding the one for which the idesired changed indication is to 'be'i'nadd It wille'i- 70 course-be understood that on 'e'achseries of such tracks T1 'and by means' of: tlieprojections ,'1 on the individual tracksz in such' series there is spelled out, in t'lie manner clearlyabo've indicated,'the-desired indic`a- 75 tion tobegiveny .f

r l desire toall attention kto the 'fact'that the pawls i1, y1 and m constitute means for preventing a backward rotation of 'the character-carrying fornis,'while the vpawls`i`1` 80 i and(11,.When` at' rest, havenstrongrtendency l to holdsuch character-carrying lormsm" a position exposing either'a blank or a character thereon galso tothe fact that the uncut lspace 4of one tooth on the ratchet wheel Pj on 85 each such character-carrying form comprisesnneans for preventing a movement of v'each characterecarrying form, whenfat :its
